RELATED APPLICATIONS

This application is a continuation-in-part of application having Ser. No. 10/877,013 (filed on Jun. 26, 2004, entitled “Mirror Sight Apparatus For Guns” and having a common applicant herewith).

FIELD OF THE DISCLOSURE

The inventive disclosures made herein relate generally to sighting apparatuses and systems for guns and, more particularly, to apparatuses and systems configured for enabling a gun to be fired from cover positions in an aimed manner.

BACKGROUND

Apparatuses that are configured for use on a gun (e.g. a rifle, a handgun, paintball gun, etc.) for permitting a shooter of the gun to fire it from a cover position in an aimed manner are known (i.e., conventional cover-position sighting apparatuses). Examples of such apparatuses are disclosed in U.S. Pat. Nos. 6,643,969; 6,311,424; 3,863,354; 3,262,440; 1,264,133; 1,260,285; 1,227,544; 880,378; 813,932; 694,904 and 187,432. In permitting a shooter of the gun to fire it from a cover position in an aimed manner, the shooter of the gun is able to remain substantially out of a line of enemy fire while being able to fire at hostile targets in an aimed manner. Firing in this manner in a hostile or potentially hostile engagement saves lives and saves ammunition, both of which are important endeavours in a hostile or potentially hostile engagement.

Such conventional cover-position sighting apparatuses are known to have limitations that adversely affect their effectiveness, desirability and/or practicality. One limitation of certain conventional cover-position sighting apparatuses is that they are inefficient in enabling a desired target to be accurately and timely acquired, even with excessive training. This is unacceptable as it puts shooters at risk and such training can often be in conflict with preferred engagement tactics. Some of such conventional apparatuses have the limitation of making a gun cumbersome due to being non-stowable, being non-removable, being difficult to remove and/or their physical size. This adversely impacts their mobility and convenience, makes them susceptible to damage and/or puts them in the way of other components of the gun. Another limitation of some conventional apparatuses is that they generate images that are distorted and/or disorienting, making it difficult to aim in an accurate and/or repeatable manner. Still another limitation of some conventional apparatuses is that they include multiple mirrors that require an undesirably high degree of alignment for enabling effective aiming. Some conventional apparatuses require a shooter to have close facial proximity to the gun in order to acquire a desired target, which is often a limitation in that this can adversely affect safety of the shooter. Yet another limitation of some conventional apparatuses is that they are overly expensive to implement, maintain and/or replace.

Therefore, apparatuses and systems configured for enabling a gun to be fired from cover positions in an aimed manner and that they at least partially overcome limitations associated with such conventional approaches for enabling firing from cover positions would be useful and novel.

DETAILED DESCRIPTION OF THE DRAWINGS

FIGS. 1-3 depict a first embodiment of a gun 10 adapted for enabling the gun 10 to be fired at a desired target from a cover position (e.g., around a corner of a wall, from over the top of an embankment, etc.) in an aimed manner. The gun 10 includes a gun body 12, a target acquisition apparatus 14 and a single-mirror target viewing apparatus 16. The gun body 12 includes a receiver 18 and a mounting rail 20 (e.g., weaver rail or picatinny rail) attached the receiver 18. The single-mirror target viewing apparatus 16 depicted in FIGS. 1-3 is an embodiment of a single-mirror target viewing apparatus in accordance with an embodiment of the inventive disclosures made herein. The target acquisition apparatus 14 and a single-mirror target viewing apparatus 16 depicted in FIGS. 1-3 jointly represent a gun sight system in accordance with an embodiment of the inventive disclosures made herein.

The target acquisition apparatus 14 and the single-mirror target viewing apparatus 16 are attached to the mounting rail 20 of the gun body 12. As depicted, the target acquisition apparatus 14 and the single-mirror target viewing apparatus 16 are discrete apparatuses mounted directly on the mounting rail 20 of the gun body 12. It is contemplated herein that, in other embodiments, (not shown), the target acquisition apparatus 14 and the single-mirror target viewing apparatus 16 may be discrete apparatuses indirectly attached to the mounting rail 20 through a separate mounting device (e.g., precision-formed interposer rail) or may be an adjoined assembly (e.g., mounted on a common support structure) that is attached directly or indirectly to the mounting rail 20.

Alternately, the target acquisition apparatus 14 and/or the single-mirror target viewing apparatus 16 may be mounted on or integrated with components of the gun body 12 other than the mounting rail 20. For example, the single mirror target viewing apparatus 16 may be an integral component of the rear iron sights on a long-barrel gun (e.g., rifle or shot gun) or may be mounted on a carry handle of a long-barrel gun (e.g., a carrying handle of a M-16 style rifle).

As depicted in FIGS. 1-3, the target acquisition apparatus 14 and the single-mirror target viewing apparatus 16 are mounted above a barrel portion 21 of the gun 10. It is contemplated herein that the target acquisition apparatus 14 and the single-mirror target viewing apparatus 16 may be mounted below the barrel portion 21 of the gun 10 or to a side of the barrel portion 21 of the gun 10. The specific mounted location will depend on factors such as shooter preference, intended application, gun configuration (e.g., hand gun, rifle, shotgun, etc.) and gun design (e.g., integral mounting devices).

The target acquisition apparatus 14 includes means for visually indicating when the gun 10 is aimed at a desired target. Examples of the target acquisition apparatus 14 include optical sight apparatuses, opto-electical sight apparatuses, and conventional mechanical sight apparatuses. An optical scope is an example of an optical sight apparatus. Trijicon brand, Docter Optic brand and EOTech brand target acquisition apparatuses are examples of opto-electical sight apparatuses that utilize laser, holographic, LED reflection and/or optical technologies. Examples of conventional mechanical sights include mechanical sights provided on the gun 10 by its original equipment manufacturer and accessory mechanical sights configured for being attached to the gun 10 after its manufacture. On a long-barrel gun (e.g., a rifle or shotgun), if an accessory front sight is required, attaching such accessory front sight on one side or both of a front tower sight construction (e.g., on an M-16 style rifle) is one preferred position. Alternatively, such an accessory front sight could be affixed to the barrel, to a barrel-insulating device or to an accessory rail that is attached to the barrel portion 21 or the receiver 18.

The single-mirror target viewing apparatus 16 includes a mirror assembly 22 and a mounting base 24. The mirror assembly 22 is movably attached to the mounting base 24. The mirror assembly 22 includes a single utilized mirror 26 (i.e., one or more redundant mirrors are contemplated) that defines a target imaging surface (e.g., reflective surface of the single utilized mirror). Preferably, the single utilized mirror 26 is essentially flat. The mounting base 24 is attached to the mounting rail 18 of the gun body 12.

The mirror assembly 22 is moveably attached to the mounting base 24 in a manner enabling the mirror assembly 22 to be pivoted and rotated with respect to the mounting base 24. In this manner, the single utilized mirror 26 is movable between a stowed position S (FIG. 3) and a deployed position D (FIG. 2) and is movable between a plurality of rotational positions. For example, the single utilized mirror 26 is movable to a first rotated position R1 (FIG. 1) for achieving a use position U and to a second rotate position R2 (FIG. 2) for enabling the mirror assembly 22 to be positioned in the stowed position S. Preferably, an axis of rotation of the mirror assembly 22 and/or the single utilized mirror 26 with respect to the mounting base 24 extends through a central region of the single utilized mirror 26. As disclosed above, the single utilized mirror 26 defines a target imaging surface, which as shown in FIGS. 1 and 2 is within the central region of the single utilized mirror 26. Thus, in at least one embodiment of the present invention, the axis of rotation of the single utilized mirror 26 extends through the target imaging surface of the single utilized mirror 26 when the single utilized mirror 26 is in a use position U. In this manner, the target imaging surface of the single utilized mirror 26 is skewed with respect to the axis of rotation of the single utilized mirror 26 when the single utilized mirror 26 is in the use position U such that the axis of rotation of the single utilized mirror 26 extends through the target imaging surface of the single utilized mirror 26 at a single point when the single utilized mirror 26 is in the use position U. Preferably, but not necessarily, the target imaging surface of the single utilized mirror 26 is skewed with respect to the axis of rotation of the single utilized mirror 26 throughout an entire range of rotation of the single utilized mirror 26 when the single utilized mirror 26 is in the deployed position D. It should be understood that the first rotated position R1 depicted in FIG. 1 is one example of a rotated position corresponding to a use position of the mirror assembly 22.

It is contemplated herein that, in an alternate embodiment (not shown) the mirror assembly 22 is positioned adjacent to one of the sides of the gun body 12 when in the stowed position S. Preferably, when in such a stowed position S, the single utilized mirror 26 faces the gun body 12 so as to protect the single utilized mirror 26 from damage. Optionally, a protective stowage enclosure (not shown) may be provided in which the single mirror is positioned when in the stowed position S.

Preferably, the mirror assembly 22 is selectively securable in the stowed position S and the deployed position D. In one embodiment, the mirror assembly 22 and the mounting base 24 are jointly configured for selectively securing the mirror assembly 22 in the stowed position S and the deployed position D. The mirror assembly 22 and the mounting base 24 including mating features (e.g., a biased positioning means and a detent) is one example of the mirror assembly 22 and the mounting base 24 being jointly configured for selectively securing the mirror assembly 22 in the stowed position S and the deployed position D.

Preferably, the mirror assembly 22 is selectively securable in one or more rotational positions (e.g., R1, R2, etc.). To this end, the mirror assembly 22 includes a base attachment portion 28 to which the single utilized mirror 26 is rotatably attached and to which the mounting base 24 is pivotally attached. In such embodiment, the base attachment portion 28 and the single utilized mirror 26 are jointly configured for selectively securing the single utilized mirror 26 in one or more rotational positions with respect to the mounting base 24. The single utilized mirror 26 and the base attachment portion 28 including mating features (e.g., a biased positioning means and a detent) is one example of the mirror assembly 22 being configured for enabling the single utilized mirror 26 to be selectively secured in one or more rotational positions.

When in the use position U, the target imaging surface of the single utilized mirror 26 is in a skewed orientation with respect to a longitudinal axis of the barrel portion 21 of the gun 10. In this orientation, a desired target and means for visually indicating when the target is acquired in an aimed manner may be viewed on the target imaging surface with the gun held in a partially rotated position (i.e., rotated along its longitudinal axis to a position between about the 12 o'clock position and about the 3 o'clock or 9 o'clock positions). Accordingly, the single-mirror target viewing apparatus 16 enables a shooter to view on the target imaging surface both the desired target and the means for visually indicating when the gun is aimed at a desired target, thereby enabling the gun to be to accurately fired from a cover position in an aimed manner.

FIG. 4 depicts a second embodiment of a gun 100 adapted for enabling the gun 100 to be fired at a desired target from a cover position (e.g., around a corner of a wall, from over the top of an embankment, etc) in an aimed manner. The gun 100 includes a gun body 112, a target acquisition apparatus 114 (i.e., front and rear physical sights) and a single-mirror target viewing apparatus 116 that is fixedly attached (i.e., non-rotating and non-pivoting) to the gun body 112. The gun body 112 includes a receiver 118 and a mounting rail 120 attached the receiver 118. The single-mirror target viewing apparatus 116 depicted in FIGS. 4 is an embodiment of a single-mirror target viewing apparatus in accordance with an embodiment of the inventive disclosures made herein. The target acquisition apparatus 114 and a single-mirror target viewing apparatus 116 depicted n FIG. 4 jointly represent a gun sight system in accordance with an embodiment of the inventive disclosures made herein.

The target acquisition apparatus 114 and the single-mirror target viewing apparatus 116 are attached to the mounting rail 120 of the gun body 112. As depicted, the target acquisition apparatus 114 and the single-mirror target viewing apparatus 116 are discrete apparatuses mounted directly on the mounting rail 120 of the gun body 112. It is contemplated herein that, in other embodiments, (not shown), the target acquisition apparatus 114 and the single-mirror target viewing apparatus 116 may be discrete apparatuses indirectly attached to the mounting rail 120 through a separate mounting device (e.g., precision-formed interposer rail) or may be an adjoined assembly (e.g., mounted on a common support structure) that is attached directly or indirectly to the mounting rail 120.

As depicted in FIG. 4, the target acquisition apparatus 114 and the single-mirror target viewing apparatus 116 are position to a right side of the gun body 112. It is contemplated herein that, in other embodiments (not shown), the target acquisition apparatus 114 and the single-mirror target viewing apparatus 116 may be positioned to a left side of the gun body 112 or a second single-mirror target viewing apparatus 116 may be mounted opposite the first single-mirror target viewing apparatus 116 (i.e., opposite the single-mirror target viewing apparatus 116 depicted in FIG. 4). The specific mounted location and number of target viewing apparatuses will depend on factors such as shooter preference, intended application, gun configuration (e.g., hand gun, rifle, etc) and gun design (e.g., integral mounting devices).

The target acquisition apparatus 114 includes means for visually indicating when the gun 100 is aimed at a desired target. Examples of the target acquisition apparatus 114 include optical sight apparatuses, opto-electical sight apparatuses, and conventional mechanical sight apparatuses. An optical scope is an example of an optical sight apparatus. Trijicon brand, Docter Optic brand and EOTech brand target acquisition apparatuses are examples of opto-electical sight apparatuses that utilize laser, holographic, LED reflection and/or optical technologies. Examples of conventional mechanical sights include mechanical sights provided on the gun 100 by its original equipment manufacturer and accessory mechanical sights configured for being attached to the gun 10 after its manufacture. On a long-barrel gun (e.g., a rifle or shotgun), if an accessory front sight is required, attaching such accessory front sight on one side or both of a front tower sight construction (e.g., on an M-16 style rifle) is one preferred position. Alternatively, such an accessory front sight could be affixed to the barrel, to a barrel-insulating device or to an accessory rail that is attached to the barrel portion 121 or the receiver 118.

The single-mirror target viewing apparatus 116 includes a mirror assembly 122 and a mounting base 124. The mirror assembly 122 is fixedly (i.e., non-rotating and non-pivoting) to the mounting base 124 and includes a single utilized mirror 126 that define a target imaging surface (e.g., reflective surface of the single utilized mirror). Preferably, the single utilized mirror 126 is essentially flat. The mounting base 124 is attached to the mounting rail 120 of the gun body 112.

When in the use position U, the target imaging surface of the single utilized mirror 126 is in a skewed orientation with respect to a longitudinal axis of the barrel portion 121 of the gun 100. In this orientation, a desired target and means for indicating when the target is acquired in an aimed manner may be viewed on the target imaging surface with the gun held in a partially rotated position (i.e., rotated along its longitudinal axis to a position between about the 12 o'clock position and about the 3 o'clock or 9 o'clock positions). Accordingly, single-mirror target viewing apparatus 116 enables a shooter to view on the target imaging surface both the desired target and the means for visually indicating when the gun is aimed at a desired target, thereby enabling the gun to be to accurately fired from a cover position in an aimed manner.

Guns configured with target viewing apparatuses in accordance with the inventive disclosures made herein are used in conjunction with a target acquisition apparatus to facilitate accurately shooting from a cover position (e.g., around a corner) with minimal or no exposure of the shooter's body. Such target viewing apparatuses are positioned generally in line with and behind an associated target acquisition apparatus. Such target viewing apparatuses include a single utilized mirror that may be adjustable to allow for tilting the gun at different horizontal angles (i.e. laid over on its side relative to the shooter). It is preferable for the mirror to be positioned so as to require the shooter to lay the gun at a minimum of approximately 45 degrees from vertical in order to use a wall or other obstacle to protect as much of the shooter's hand as possible. For left-handed shooting (i.e., the right side of the gun exposed to the shooter) on guns with a right side ejection port, it is preferred that the mirror be positioned so as to require that the gun be laid over to a degree where cartridges will not be ejected into the shooter's face.

Use of target viewing apparatuses in accordance with the inventive disclosures made herein in conjunction with handguns to facilitate accurately shooting from a cover position is contemplated. Generally, the underlying configuration discussed above in reference to long barrel guns also applies to handguns. In one embodiment specific to handguns, the target viewing apparatus and an opto-electrical target acquisition apparatus are mounted beneath the barrel of the handgun. Accordingly, the shooter can accurately aim and shoot around a corner by utilizing the mirror to acquire the target and to aim. Preferably, adjustability of the mirror is restricted so as to require the shooter to orient the gun in a non-vertical orientation. The non-vertical position serves the purpose of helping to protect the shooter's hand behind cover and also protect the shooter's face from shells that are being ejected out of the gun.

FIGS. 5-7 show a targeting system in accordance with the present invention, which is referred to herein as the targeting system 200. The targeting system 200 includes a mounting rail 202, a single-mirror target viewing apparatus 204, a target acquisition apparatus 206 and a mirror shrouding apparatus 208. The single-mirror target viewing apparatus 204, the target acquisition apparatus 206 and the mirror shrouding apparatus 208 are fixedly mounted on the mounting rail 202. The mounting rail 202 is of a standard configuration (e.g., industry standardized) for being attached to a receiver or other portion of a gun and for having accessory items mounted thereon. Alternatively, the mounting rail 202 may be integrally formed with the receiver or other portion of a gun.

The single-mirror target viewing apparatus 204 is mounted adjacent a first end portion 210 of the mounting rail 202 and the target acquisition apparatus 206 is mounted adjacent a second end portion 212 of the mounting rail 202. In this mounted configuration, the single-mirror target viewing apparatus 204 is in spaced-apart relationship with the target acquisition apparatus 206 with respect to a longitudinal axis L1 of the mounting rail 202. The mirror shrouding apparatus 208 extends from adjacent the single-mirror target viewing apparatus 204 toward the first end portion of the mounting rail 202.

The target acquisition apparatus 206 includes means for visually indicating when a gun on which the targeting system 200 is mounted is aimed at a desired target. Examples of the target acquisition apparatus 206 include optical sight apparatuses, opto-electical sight apparatuses, and conventional mechanical sight apparatuses. An optical scope is an example of an optical sight apparatus. Trijicon brand, Docter Optic brand and EOTech brand target acquisition apparatuses are examples of opto-electical sight apparatuses that utilize laser, holographic, LED reflection and/or optical technologies. Examples of conventional mechanical sights include mechanical sights provided on a gun by its original equipment manufacturer and accessory mechanical sights configured for being attached to the gun after its manufacture. On a long-barrel gun (e.g., a rifle or shotgun), if an accessory front sight is required, attaching such accessory front sight on one side or both of a front tower sight construction (e.g., on an M-16 style rifle) is one preferred position. Alternatively, such an accessory front sight could be affixed to the barrel, to a barrel-insulating device or to an accessory rail that is attached to a barrel portion or a receiver potion of the gun.

The single-mirror target viewing apparatus 204 includes a mirror assembly 214 and a mounting base 216. The mirror assembly 214 is movably attached to the mounting base 216. The mirror assembly 214 includes a single utilized mirror 218 (FIG. 7) that defines a target imaging surface (e.g., exposed reflective surface of the single utilized mirror 218). Preferably, but not necessarily, the single utilized mirror 218 is essentially flat. The mounting base 216 is attached to the mounting rail 202 by a clamping structure 219 (FIG. 5).

The mirror assembly 214 is moveably attached to the mounting base 216 in a manner enabling the mirror assembly 214 to be pivoted between a plurality of positions with respect to the mounting base 216 and to be rotated between a plurality of rotational positions with respect to the mounting base 216. In this manner, the single utilized mirror 218 (i.e., in combination with the mirror assembly 214) is movable between a stowed position S (FIG. 5), a mirror use position U (FIG. 7) and a sighting device use position U2 (FIG. 6). The stowed position S and the a sighting device use position U2 are both examples of mirror non-use positions in accordance with the present invention.

As discussed below in greater detail, when the single utilized mirror 218 is in the mirror use position U, the single-mirror target viewing apparatus 204 enables a shooter to view on the target imaging surface of the single utilized mirror 218 both a desired target and the means for visually indicating that the gun is aimed at a desired target. As is discussed below in greater detail, when the single utilized mirror 218 is in the sighting device use position U2, a sighting device attached to the mirror assembly 214 is in a respective use position.

Preferably, an axis of rotation of the mirror assembly 214 and/or the single utilized mirror 218 with respect to the mounting base 216 extends through a central region of the single utilized mirror 218. As disclosed above, the single utilized mirror 218 defines a target imaging surface, which as shown in FIG. 7 is within the central region of the single utilized mirror 218. Thus, in at least one embodiment of the present invention, the axis of rotation A1 (FIG. 7) of the single utilized mirror 218 extends through the target imaging surface of the single utilized mirror 218 when the single utilized mirror 218 in the mirror use position U. In this manner, the target imaging surface of the single utilized mirror 218 is skewed with respect to the axis of rotation A1 of the single utilized mirror 218 when the single utilized mirror 218 is in the mirror use position U. Accordingly, the axis of rotation A1 of the single utilized mirror 218 extends through the target imaging surface of the single utilized mirror 218 at a single point when the single utilized mirror 218 is in the mirror use position U and is skewed with respect to the longitudinal axis L1 of the mounting rail 202. Preferably, but not necessarily, the target imaging surface of the single utilized mirror 218 is skewed with respect to the axis of rotation A1 of the single utilized mirror 218 throughout an entire range of rotation of the single utilized mirror 218. It should be understood that the mirror use position U depicted in FIG. 7 is one example of a rotated position, which so happens to corresponding to a particular mirror use position of the mirror assembly 214. Preferably, but not necessarily, the mirror assembly 214 is rotatable a fully 360 degrees or, at least a substantial portion thereof.

Preferably, the mirror assembly 214 is positively positioned (i.e., selectively securable) in the stowed position S, the sighting device use position U2 and the mirror use position U. To this end, a first positive positioning structure is provided between the mirror assembly 214 and the mounting base 216 and a second positive positioning structure is provided between the single utilized mirror 218 and a base attachment portion 220 (FIG. 5) of the mirror assembly 214. The positive position structures jointly enable the single utilized mirror 218 to be positively positioned in a plurality of predefined positions. The mirror use position U, the sighing device use position U2 and the stowed position S are examples of such predefined positions.

In one embodiment, the positive positioning structures each include a locating member than engages a mating feature for facilitating such positive positioning. With respect to the first positive positioning structure, an example of such a structure includes a spring loaded element of the mounting base 216 that selectively engages each one of a plurality of mating feature of the base attachment portion 220 for providing positive positioning of the mirror assembly 214 with respect to the mounting base 216. The plurality of mating features (e.g., detent features) are provided in spaced apart relationship with respect to each other for enabling positive positioning of the base attachment portion 220 at positions corresponding to the mirror use position U, the sighting device use position U2 and the stowed position S. It is disclosed herein that the relative association of the locating member and a mating feature with the mounting base 216 and the base attachment portion 220 may be reversed while still providing positive positioning functionality. With respect to the second positive positioning structure, an example of such a structure includes a spring loaded element of the base attachment portion 220 that selectively engages each one of a plurality of mating feature of a mirror casing 222 of the single utilized mirror 218 for providing positive positioning of the single utilized mirror 218 with respect to the base attachment portion 220. The plurality of mating features (e.g., detent features) are provided in spaced apart relationship with respect to each other for enabling positive positioning of the mirror assembly 214 at positions corresponding to the mirror use position U, the sighting device use position U2 and the stowed position S. It is disclosed herein that the relative association of the locating member and a mating feature with the base attachment portion 220 and the mirror assembly 218 may be reversed while still providing positive positioning functionality.

Referring now, to FIGS. 8-10, the single-mirror target viewing apparatus 204 includes a sighting device 224 attached to a rear surface of the mirror casing 222. The single utilized mirror 218 is attached to a front surface of the mirror casing 222, which is opposite the rear surface. The sighting device 224 includes an alignment member 226 having two sighting structures. The alignment member 226 is pivotably mounted on a windage adjustment screw 227. A first sighting structure 228 is angularly offset from a second sighting structure 230 with respect to longitudinal axis L3 of the pivot member the windage adjustment screw 227 whereby pivoting of the alignment member about the longitudinal axis L2 of the windage adjustment screw 227 allows each one of the sighting structures (228, 230) to be moved to a sighting structure use position U2. A positive positioning structure is provided between the alignment member 226 and the mirror casing 222 for enabling each one of the sighting structures (228, 230) to be selectively and positively positioned in the sighting structure use position U2.

The first sighting structure 228 includes a first aperture 229 (i.e., a first sighting feature) having a first diametrical size. The second sighting structure 230 includes a second aperture 231 (i.e., a second sighting feature) having a second diametrical size different than the first diametrical size. The depicted apertures (229, 231) are examples of two different sighting features. In addition to the sighting features in accordance with the present invention being different size, it is disclosed herein that such sighting features can be shapes, relative positioning with respect to the longitudinal axis L2 of the windage adjustment screw 227, etc.

When the single-mirror target viewing apparatus 204 is properly attached to a gun and when a sighting feature of the alignment member 226 is in the sighting structure use position U2, that sighting feature is alignable with a mating alignment member of a companion sighting device (e.g., a front sight of the gun) when the single utilized mirror is in the sighting device used position U2. Such alignment provides for precision aiming of the gun through combined use of the sighting device 224 and the companion sighting device.

The alignment member 226 is mounted in a manner enabling independent adjustment for windage and for elevation. Adjustment for windage refers to lateral adjustment of the alignment member 226 along to the longitudinal axis 2 of the windage adjustment screw 227. Adjustment for elevation refers to vertical adjustment of the alignment member 226 along a vertical reference axis V1 extending through the longitudinal axis L2 of the windage adjustment screw 227.

For enabling windage adjustment, the windage adjustment screw 227 is mounted on a support member 232 whereby rotation of the windage adjustment screw 227 causes lateral translation of the windage adjustment screw 227 (i.e., along the longitudinal axis L2). The alignment member 226 is mounted on the windage adjustment screw 227 in a manner that enables pivoting of the alignment member 226 relative to the windage adjustment screw 227 and that substantially precludes lateral movement of the alignment member 226 with respect to the windage adjustment screw 227. Thus, lateral translation of the windage adjustment screw 227 results in a corresponding lateral translation of the alignment member 226.

For enabling elevation adjustment, the support member 232 is mounted on the mirror casing 222 in a manner enabling the support member 232 to be pivoted about a longitudinal axis L3 of a pivot member 234. The longitudinal axis L3 of the pivot member 234 extends parallel to the longitudinal axis L2 of the windage adjustment screw 227. An elevation adjustment screw 236 is engaged between the support member 232 and the mirror casing 222. Rotation of the elevation adjustment screw 236 causes the support member 232 to pivot correspondingly about the longitudinal axis L3 of the pivot member 234, thereby resulting in vertical movement of the alignment member 226 along a vertical reference axis V1.

Referring to FIG. 10, accuracy of aiming with the sighting device 224 requires repeatable and precise repositioning of the single utilized mirror 218 in the sighting device use position U2. Once the alignment member 226 is adjusted for windage and elevation with respect to companion sighing device, the degree of precision to which the single utilized mirror 218 can be repositioned in the sighting device use position U2 largely impacts accuracy in aiming. To thus end, a locking structure is provided between the mounting base 216 and the mirror assembly 214 for enabling the mirror assembly 214 to be fixedly retained in the sighting device use position U2 (i.e., a non-use position relative to a position in which the mirror assembly 214 is used). The locking structure includes a locking member 238 movably attached to the mounting base 216 and a slot 240 in the mirror casing 222 (i.e., a mating engagement feature fixedly attached to the mirror assembly 214). The locking member 238 is selectively movable between an engaged position E (i.e., within the slot 240) and a disengaged position D (i.e., removed from the slot 240). The locking member 238 is captured within the slot 240 (i.e., engages the mating engagement feature) when moved to the engaged position E while the mirror assembly 214 is in the sighting device use position U2, thereby jointly constrains movement of the single utilized mirror 218 with respect to the base attachment portion 220 and the mounting base 216. Additionally, the locking member 238 and the slot 240 are jointly configured (e.g., size, shape material, etc) whereby engagement of the locking member 238 within the slot 240 provides for precision repositioning (i.e., also referred to as zeroing) of the mirror assembly 214 in the sighting device use position U2.

Referring to FIGS. 5, 6, 11 and 12, the mirror shrouding apparatus 208 includes a mirror shrouding body 242 having an attachment region 244 engagable with the mounting rail 202 for enabling the mirror shrouding body 242 to be attached to a mating structure of a gun (e.g., an receiver, a barrel cover, integral mounting rail, etc) or an accessory item (e.g., a single-mirror target viewing apparatus 204 in accordance with the present invention). It is disclosed herein that the attachment region 244 may alternatively be configured for being engaged with the mating structure of a gun or the accessory item. It is further disclosed herein that the attachment region 244 may include an integral retention device (e.g., set screw or clamp arrangement) that secures the mirror shrouding apparatus 208 in place on the mounting rail 202 or may include an interlock feature that engages a mating interlock feature of the single-mirror target viewing apparatus 204 such that securing the mirror shrouding apparatus 208 in place on the mounting rail 202 via the clamping structure 245 (FIG. 8) of the mounting base 216 correspondingly secures the mirror shrouding apparatus 208 in place on the mounting rail 202.

When the mirror assembly 214 is in the stowed position S (FIG. 5) or the sighting device use position U2 (FIG. 6), the position, size and/or shape of the mirror shrouding body 242 with respect to that of the mirror assembly 214 serves to preclude all beams of light reflected by the target imaging surface from being visible at any remote location relative to the single-mirror target viewing apparatus 204 with the single-mirror target viewing apparatus 204 in any orientation (i.e., with the single-mirror target viewing apparatus 204 staying in a fixed position with respect to the mirror shrouding apparatus 208). In effect, the mirror shrouding body blocks all reflected beams of light after the beams of light impinge upon the target imaging surface of the single utilized mirror 218. In providing such functionality, the mirror shrouding body 242 precludes beams of light from impinging upon the target imaging surface of the single utilized mirror 218 and/or blocks a reflected portion of the beams of light after the beams of light impinge upon the target imaging surface of the single utilized mirror 218.

The mirror shrouding body 242 includes a mirror casing receiving recess 246 (FIGS. 6 and 11). The mirror casing receiving recess 246 has disposed therein at least a portion of the mirror casing 222 of the single-mirror target viewing apparatus 204 when the single utilized mirror 218 is in the stowed position (i.e., a non-use position with respect to use of the single utilized mirror 218). The mirror casing receiving recess 246 advantageously permits spacing between the mirror shrouding body 242 and the single utilized mirror 218 to be maintained at a minimum distance when the single utilized mirror 218 is in the stowed position S and the sighting device use position U2.

Referring now to FIGS. 13 and 14, the mirror shrouding body 242 includes upstanding members 248 and an upper edge portion 251 of the mirror casing 222 includes upstanding member receiving recesses 250 therein. The upstanding members 248 engage the upstanding member receiving recesses 250 when the single utilized mirror 218 is in the stowed position S. When engaged, the upstanding members 248 and the upstanding member receiving recesses 250 jointly carry a load resulting from an externally applied force exerted on the mirror casing 222 thereby limiting deflection of the mirror casing in the downward and/or lateral directions. In doing so, the upstanding members 248 and the upstanding member receiving recesses 250 jointly reduce the potential for the externally applied force resulting in damage to the mirror assembly 214. It is disclosed herein that the upstanding member receiving recesses 250 may be provided in another region of the mirror casing 222 as opposed to the upper edge portion 251 of the mirror casing 222 (e.g., side edge portions).

Still referring to FIGS. 13 and 14, the mirror casing 222 includes a mounting rail receiving recess 252 in the upper edge portion edge 251. The mounting rail receiving recess 252 engages the top face of the mounting rail 204 when the single utilized mirror 218 is in the stowed position S. When engaged, the mounting rail receiving recess 252 and the mounting rail jointly carry a load resulting from an externally applied force exerted on the mirror casing 222 thereby limiting deflection of the mirror casing in the downward and lateral directions. In doing so, mounting rail receiving recess 252 and the mounting rail jointly reduce the potential for the externally applied force resulting in damage to the mirror assembly 214.
